knowledge? what knowledge? that was my first build. I didnt know anything about swapping anything.. I just wanted it so bad that i just threw myself to the wolves... you know that saying ("you can do anything if you put your mind to it") well its true.. i am proof of that. if you want it bad enough, you will learn along the way how its done, trust me

What's your exhaust routing look like? I see shorty headers in the thread, but don't see if you ran duals, duels with an "x" pipe, or just merged to a single exhaust.

You're power numbers are impressive, I assume rwhp in your sig? Do you have a chart? I have a couple more cubes (LS7 block - 427) but lower numbers at 407 hp/448 tq. I'm using truck manifolds that merge to a single 3" to a single Flowmaster 50.

I'm just wondering where the difference is coming from or if you have more top end and perhaps I get more earlier and less up top.

Eliminator, how about the finished product in action. I know it's an older build now but would love to see your TJ in action with the new motor. YouTube video sounds great but would love to see acceleration.

Thanks, I'm curious about the exhaust as well. The speed shop tuning the motor for me is recommending larger headers. I'm running the sanderson ls block hugger style too. They built me a 3" exhaust that's a full 3" from the collector flange, the. Y's into one single. They're recommending larger headers with atleast 1.75" primaries and 3" collectors.... Since you're already where I want to be I don't see the need for the header change.

Are you still running your original gear/tire combo?

Fattire what's your gear/tire?

Mine is geared at 4.88 and I'm running 35" MT's...wondering if I'll want to regear later.

Nice build BTW!

i have true dual set up, no cats, ill get video and /or pics soon as i make it back to the beach. I am in the gulf as of now

yeah same gear set up.37in and 4.56's
Are they recommending you to swap out your sanderson shortys that are 1.75 ?

Yes, they're saying that the only restriction in my exhaust side now are the headers. They're saying the sandersons are good for a standard 5.3 but with the 6.0 cammed and ported they recommend 1.75 primaries and 3" collectors at a minimum. I'm running a 3" y exhaust set up to a single exit so with you having true duals you may not have the same restriction. Here's the exhaust they ran for mine, very clean and all stainless. 3" all the way from the collectors. For state inspection we have visual and sniffer so I had to use a hi flow cat and used a magnaflow muffler.

Yes they are a bit on the high side but these meters will get your attention long before anything gets damaged.. They pay for them-self. Trust me. You can diagnose a problem very quickly with these gauges. For an example, I needed constant 60 psi of fuel pressure, but when I put the hammer down, fuel pressure would drop causing the fuel gauge to flash. That right there told me my pump wasn't up for the job. Awesome gauges!!! Try you tube for Autometer elite series gauges

I regret not going with the in dash fuel pressure gauge. Probably do one later on, you did it right the first time. I have one on the fuel rail but with DBW really takes two to rev and see what the pressure does. And even then it doesn't really measure under load. I'd much rather have live monitoring.
